Getting Started

Build a native desktop app in TypeScript in under 5 minutes. By the end of this section you’ll have:

a running dev window with HMR on both the frontend and the backend,
a typed RPC boundary — rename a function in backend/main.ts and the TypeScript compiler catches every stale frontend call,
a single-file .exe / binary in release/, around 6.6 MB for lite or 44 MB for full, that you can ship as-is.

Bun is required. On Linux you also need the WebKitGTK dev packages — see Installation.


bunx @tynd/cli create my-app

The CLI asks for a project name, a frontend framework (React, Vue, Svelte, Solid, Preact, Lit, or Angular), and a runtime mode (lite or full).


cd my-app
bun run dev

A native window opens with your frontend + HMR. Save backend/main.ts — the backend hot-reloads without tearing down the window.


tynd build            # raw binary
tynd build --bundle   # + platform installers (.app/.dmg, .deb/.rpm/.AppImage, NSIS/MSI)

Output lands in release/.

Bun, WebView deps per OS, verifying the setup.

Walk through the backend, the frontend, and the RPC boundary.

What each file does and where your code goes.

tynd dev vs tynd start, caching, hot reload.
